DIRECT-ACTING PUMP.

SPECIFICATION forming part of Letters Patent No. 766,237, dated August 2, 1904.

Application filed August 24,1903. Serial No- 170,512. (No model.)

To aZZ wlwm it may concern.-

Be it known that I, HAMLIN F. FRISBIE, a citizen of the United States, residing in the city of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Direct-Acting Pumps; and I do declare the following to be a clear, full, and exact description thereof, attention being called to the accompanying two sheets of drawings, with the reference characters marked thereon, which form also a part of this specification.

This invention relates to improvements in the construction and arrangement of directacting pumps that is, such where the plunger-rod of the pump is immediately connected to and directly actuated by the piston-rod of the steam-engine or equivalent member of the driving-motor and where a fly-wheel is provided to obtain an even and regular motion of the parts to maintain by it a constant operation of the pump.

My invention consists of the construction, in general and in particular, whereby the provision of a fly-wheel on such a pump is accomplished and of certain features relating to the general construction of the combined outfit.

In the following specification, and particularly pointed out in the claims at the end thereof, is found a full description of the invention, together with its operation, parts, and construction, which latter is also illustrated in the accompanying drawings, in which- Figure 1 shows in a side view a pump and a steam-engine operatively connected thereto for operating it and all arranged and constructed so as to conform to the plan of my invention. Fig. 2 is a top view of the preceding tigurc. Fig. 3 shows the central part of Fig. I in longitudinal section. Fig. 4 is a cross-section on line 44 of Fig. 2.

10 is the pump-cylinder, and 11 11 are chambers containing the receiving or suction valves 12. These valve-chambers are in open communication with a so-called side pipe 13, to which the supply-pipe connects by means of the intake-nipple 14, so that either valve is in open communication with the supply and may draw from the same.

15 15 are the chambers containing the discharge-valves 16 and communicate also with a side pipe 17 and a nipple 18,from which the combined discharge takes place. The object of using these side pipes is to consolidate the action of these valves, so as to have the suction-valves draw from one supply-pipe and also using one outlet for the discharge-valves. 19 is the customary air-chamber. The planger which moves inside of the pump-cylinder for the purpose of operating these valves is provided with a plunger-rod 21, which for the purpose of actuating said plunger is connected to the piston-rod 22 of the steam-engine, of which 23 is the cylinder, both rods being alined. The connection of these two rods is preferably by a coupling-piece 24, which may be either entirely independent or integral with one of the rods, the other rod being then rigidly connected. The steam-engine may be of a type most suitable for the purpose. As shown, it is of the slide-valve type, 25 being the valve-chest containing the valve which controls the supply to the steam-cylinder for operating the steam-engine.

26 is the valve-rod connecting to the valve and to a rocker-arm 27, projecting from a rock-shaft 28, supported on a standard 29.

In order to give to this directly-operatcd pump the advantage of the equalizing effect of a fly-wheel, one is provided, as shown at 31, the same mounted on a shaft 32, which is supported in bearings 33. This shaft isrotated by means of a crank 34, operated by a connecting-rod The other end of this latter connects to a slide-rod 36, mounted in bearings 37, attached so as to hold this slide-rod to a motion parallel to the movement of the piston-rod. Both are connected to each other by means of a tie-joint 38, so that both move together and as one.

It will now be seen that the steam-engine by reciprocating slide-rod 36 rotates also the fly-wheel simultaneously with the operation of the pump, so that this operation is thus brought directly under the equalizing and controlling efl'ect of the fly-wheel. The unequal and spasmodic operation of direct acting pumps devoid of a liy-wheel is thus avoided. Coupling 24 is slotted, as shown, to permit placing of shaft 32, and said coupling may be guided in a way 39, formed between bearings 33. This guideway and these two bearings may be contained in one combined structure or stand 41. The rotation of this shaft is also utilized to actuate the slide-valve of the engine, which is done by a customary eccentric 42, connecting to an arm 43 on rockershaft 28. This particular construction of the means for operating the valve is, however, immaterial and may be modified to suit the particular kind of valve and steam-engine.

All the parts described-that is, pump-cylinder 10, structure 41, and steam-cylinder 23 are supported on a one-piece bed-frame H, shaped as shownthat is, consisting of two sections, a lower one upon which the pump rests and one at a higher elevation to suit the position of the steam-engine. The outer end of the higher frame-section, is supported by a legfio and by an upright frame-section 44, which connects also the higher and lower parts of the bed-frame.

Clearance of shaft 32 by coupling member 24 might be obtained otherwise than by slotting said memberas, for instance, said member if properly supported and guided at its ends might be merely curved around said shaft.

Having described my invention, I claim as new i 1. In a direct-acting pump, operated by a steam-engine, and where the plunger-rod of the pump and the piston-rod of the steam-engine are connected to each other, the combination of afly-wheel, a crank-shaft upon which it is mounted, hearings in which this shaft is supported at right angles to the connectingrod, a slide-rod supported so as to have a reciprocating motion parallel to and coextensive with the piston-rod of the steam-engine, means whereby the two are connected to each other so as to move as one, and a connectingrod between this slide-rod and the crank-shaft for operating this latter.

2. In a direct-acting pump operated by a steam-engine, the combination of a slotted coupling member uniting the outer ends of the plunger-rod and the piston-rod to each other, a guide in which this coupling member is supported for movement, a fly-wheel, a shaft upon which it ismounted, bearings for it, one projecting from each side of the guide mentioned and whereby said shaft is supported so as to be disposed at right angles to this coupling member and passing through the slot thereof and operative connection whereby this shaft is rotated by the piston-rod of the steam-engine.

3. In a direct-acting pump where the plunger-rod of the pump and the piston-rod of the steam-engine are directly connected to each other, the combination of a unitary bed-frame consisting of two integral sections, one arranged at a lower level to receive and support the pump-cylinder, the other at a higher level to receive and support the steam-engine, an upright junction member which integrally connects these two'frame-sections and a leg under the outer end of the higher frame-section.

4. In a direct-acting pump operated by a steam-engine, the combination of alined plunger and piston rods connected to each other, a shaft alined in plan with them, hearings in which it is supported at right angles to the rods mentioned, a slot provided in the intermediate portion of the connected rods to clear the shaft, a fly-wheel at one end of this latter, a crank at the other one, a central guide between these two, to sustain the slotted portion of the connected rods and operative connection between this crank and the parts actuated by the steam-engine, to operate the crank.

In testimony whereof I hereunto set my signature in the presence of two witnesses.
